In general the inventive concept of the present applicationmay be' dened as being carried out by the provision of a flexible screen which is secured within a return bent portion of an edge holdingV strip vtogether with securing means for the strip engaged within the same return bent portion. vIn Vso locating the securing means within the channel which receives the screen edge, the securing means act to assist in locking the screen in position; 'While the securing means may be permanently and rigidly locked inthe channel, such means. are preferably mounted to slide therein sc as to.n permit adjustment at the place of installation.' The invention also provides means for securing'arsealing strip Within the edge holding strip so as to vprovide an effective and efiicent seal between such strip and a window frame. i

Referring nowmor'e particularly to the drawings, .in'Fig. 1 the blindstop vof the frame is indicated by the numeral.lll,while the Vnumeral I I illustrates Ythe-lower sill of the frame. A woven wireor fabric screen-is identied by the numeral I2, its upper and lower edges being received within the return 'bent portion I3 of upper and lower screen holding strips I4 and I5 respectively. In both- Ainstances ythe return bent portion I3 forms a channel I6 in-which the screen edge is lodged. The screen edge, a's illustrated, is preferably return bent' within the channel I6 to secure it against accidental displacement therefrom. S Y

The upper holding strip- I4 is formed-in addi- Y tion t-o the return bent portion I3 with an outwardly extending ange Ill; which Vis, adapted to bear-against'and seal'fthe-o'uter face I8 of the blind stop' iIIl. For scuring the upper strip I4 to the blind stop I!) there is provided a securing member generally indicated by the numeral I9. The member I9 is generally U shaped in crosssection and includes an upper horizontal wall 2D and a parallel lower horizontal wall 2I joined by an intermediate vertical wall 22. The free outer edge ofthe upper wall 20 is turned at right angles thereto toform achannel engaging flange 23 which ismounted Awithin the channel It and in contact with the screen edge located therein. While the flange 23 is in frictional contact with the inner Wall of the channel and withfth-e screen edge to assist in securement of the screen within the channel, it is longitudinally slidable to permit adjustment thereof. As indicated. at y24, the flange II is inwardly `offset withrespect tothe outer wall of the return bent portion. I3 so as to form a shoulder whichengages the right-iangular bend ofthe wal1--2 with respect to the ange 23 and thus to rengage the securingmember I9 to preclude dislodgement of the flange-.23 from the channel by transverse movement thereof with respect to the strip. For attaching the securing means to the: blind stop I5, an attaching screw 25 is provided .the shankfof which passes through registering apertures 126- inthe `upper and lower wallsV 20 .and 2 I.,. respectively, so vas to engage the shank at spaced points,-thus precluding a pivotal movement of the securing means I9 with respect tothe screw and with respect to the frame .IIL x w 'a By this construction it will be seen that the strips 'I4 may be formedatthe factory of indennitelength and a screenr may belocated in the channel thereof and the securing means I9 loosely applied at` such'intervals .as may be Vfound required. As specications for the window frames to which the screen is to beapplied are received the strip members I4 and their companion `mem-` bers I5may'be cut to the desired length and the securing means moved-"longitudinally to the approximate point assumedto'bedesirable and suchk screens may then be delivered. When the positicnvfor thescrews 25 is determined-the securing means I9 are slipped longitudinally,V of Vthe strip andthe screwsare then inserted, fthus permanently attaching the securing means in their newly'located position and acting in lsuch position to assist `in .retaining theA screen edge within the channel I5. ySince the securing means is slidable with respect to the strip. I4, it can be formed to releasablyengage the screw by use of a bayonet slot opening entering. through the vertical wall 22 if desired. f f p By further reference to Fig. l and with reference to Figs. 3 and 4itiwill be seen that th-e lower securing means. for the: lower strip l'comprises end securing elements having verticalflanges 2'I which are slidably .mounted Within the channel ofthe lower strip I5 andare engageable. with the'` edge portion of the screen folded-within the channel in the same .manner as the flange 23 with the upper securing member. curing strip I5. is also provided with an inturned shoulder 2S similar to the 'shoulder 24 and a downwardly. ext-ending flange 29 comparable with the flange I'I. of the upper. strip I4. At the terminable edge of theflange 29, however, the lower securing strip I5 is formed with an outwardly turned flange 'll'terminating in adownwardly extending lip. 3I :forming an extension which-is adapted to -lie overfthe upper face of the sill II. The flange2'I of thelower securing member, generally indicated by the numeral 32, is formed with a shoulder 33 engageable with the shoulder 2B in order to preclude outward movement of the flange with respect to the channel and the shoulder 33 is formed with a downwardly extending nange 3'4 which terminates in an outwardly extending surface 35 disposed at slightly obtuse angle with respect to the ange 34. The outer edge of the surf-ace 35 is provided with an upwardlyextendingfilange 36 which forms `a manipulating handle for the lower end securing means.

For sealing the lower strip with'respect to the surface of the sill II, there is provided a vertically .adjustable sealing element 31 having an upper curved head 318 adapted to form frictional engagement .with the innersurface of the flange 34 of the securing means. The flange 34 of the securing means is Yalso provided with a detent 39 adapted to engage the inward facing surface of the member 31 to form a frictional lock thereforwhereby it will be retained in its downwardly adjustedposition for` sealing 'engagement with the surfaceofthe .sill lIL nThe'lower end of the member, 31 is outwardly turned, as indicated at 40, in parallelism with .the .end of 30 of the flangel 29,.thus acting .in conjnnctiontherewith to .seal the surface II..-

- K For engaging the securing means with the sill Il, .a keyholefslotis provided, itshead opening 4I 'being located in .the 'lowerportion of the vertically extendedvangef, while the elongated shank ofY theppeningi indicated at y42, extends into the inclined surface of. the .portion` 35 of the securingmeans andterminates in a slight recess .indicated-at 43',.which is adapted to receiveithe head 44-.of an attaching screw 45. By

this. arrangement :ity will be seen that the enlarged opening'i may readily receive the head 44 vof the screw. 45. Ifnwardmovement of the securing vmeans-.will Vcause .the surfacey adjacent the shank .portion`42 of. the slot to be engaged underk theA head kllllofthe screw whereby continued inner movement .of the securing means will-camL thesecuring member downwardly to tensionthefscreenfand to force the sealing mem- The lower seber .31 into sealingh engagement. with the surface of the sill I I. The nal lodgement of the head 4S within the recess-43 atthe inner. end ofthe shank of the keyhole. openingis such as to preclude 'accidental displacement ofthe securing means from the-head.

In the .construction and arrangement of parts shown in Fig. .4, it will be noted that only two end securing elements 32 areemployed. However, a central. element .46 is provided and is somewhat similar thereto.v The member 46 is similarto the securing means in thatit is provided with a flange 41 lodged withinthe .channel IB, which iiange is :slidable within ythe' vchannel and engages the edge of thescreen in order to-assist in securing Athe Ysame within the channel. The member 4t is .likewise similar .to the securing member 32 in being providedwith a detent 43 vwhich engages the inner face of the sealing member 31 in order to cooperate with the head 38 to secure vthe sealing-member in'its vertically adjusted position.

Referring nowto Figsj, 6, '7 and 8 of the drawings, itwill be seen that the specic means of attaching the securing means tothe frame may take-form otherthan that disclosed in Figs. 1 to 4, inclusive. InFig. 6, the upper securing strip I4 is identical with that shown in Figs. 1 and 2, and within thechannel I5 thereof are located the upper Vvedge vof V.the screen I2 Vandthe flange 23 of a securing means, which isslidable but locked against accidental displacement from the channel vby the inwardly turned shoulder 24. In this form of the invention, 1n lieu of thel substantially U-shaped body which engages at spaced points the shank of the screw 25, the screw 25 is received through a simple inwardly directed slot 49 of a flange 50 extending at right angles to the flange 23 seated within lthe channel I6. An outer lip 5I is formed at the free edge of the flange 50 in order to preclude accidental dislodgement of the member from the head of the screw 25.

The lower screen securing strip of that form of the invention shown in Fig. 5 is identical with the strip I5 of Fig. 1 in that it has the return bent portion I3 forming the channel I6 for receiving the flange 21 of the securing means. The shoulder 28 engages the Shoulder 33 ofthe securing means to lock the iiange against accidental movement from the channel. In lieu of the sealing strip 31 of Fig. l, the lower strip of Fig. 5 is formed with a simple downwardly extending iiange 52 which has fitted over the edge thereof a return bent sealing strip 53 which is frictionally slidable on the edge of the iiange 52 to provide a seal against the upper surface of the sill I I of the bottom strip of Fig. 5, including a bifurcated engaging piece 56, the outer ends of which are turned downwardly to form catch hooks 55.

When the lower strip is to be secured, the hooked` ends 55 of the bifurcated member 54 engage the upper outer corners 56 of the bracket 51, which bracket is rigidly secured to the surface II by a screw, or the like, indicated at 58. The bracket 51 is also provided with an aperture 59, through which extends a securing bolt 6B provided with a wing nut 6I. In attaching the device the wing nut is loosened on the bolt 60 and the bifurcated members moved inwardly to straddle the shank of the bolt 60 and to engage the hooked ends 55 with the corners 56. Thereafter the wing nut 6I may be tightened outwardly on the shank of the bolt 60 and in such tightening movement the securing means 54 rocks about the corners 55, thus lowering the outer end of the securing means and applying tension on the screen and causing the sealing member 53 to snugly engage the surface of the sill II to seal the same.

A further form of the invention is disclosed in Figs. 8 and 9 in which the channel engaging portion of the securing means generallyindicated by the numeral is formed by lips 1I stuck out from an upward extension 62 of a body flange 63. In other respects the securing means is in conformity with thev structure of Fig. 1. It will be noted that the extension 62 is co-planar with the body flange 63 and thus provides an internal surface which bears against the lower portion of the screen to secure the screen between it and the outer face of the return bent portion I3 of the holding strip I5. The lips 1I, while slidable in the channel I6, also act in the manner of the flange 21 to assist in the screen securement.

From the foregoing it will be seen that the present invention provides a novel, simple and improved construction and arrangement of parts whereby readily adjustable securing means is mounted with respect to a screen engaging strip and whereby such securing means acts in conjunction with the strips as a means for assisting in securing the screen within the channel. It will, of course, be understood that theinvention is not limited to the specific Structure here shown and that numerous changeaimodiiications and the full use of equivalents may be resorted to in the practice of the invention without departing from the spirit or scope of the same, as outlined in the appended claims.l
